In the United States, Quantinuum, a quantum computing company, successfully raised $1.68 billion in its initial public offering (IPO) on June 4, 2026. The company offered 28 million class A common stock shares, which began trading at $60 each on the Nasdaq Global Market. This amount exceeded the initial estimate of $1.5 billion that was projected when the company filed for its IPO just over three weeks prior. The offering was increased from an anticipated 26.5 million shares and priced above the marketed range of $53 to $55 per share, ultimately valuing Quantinuum at approximately $15.6 billion. Quantinuum, which is backed by Honeywell International, has also granted underwriters a 30-day option to purchase an additional 4.2 million shares to cover over-allotments at the initial public offering price, minus underwriting discounts and commissions. JP Morgan and Morgan Stanley served as joint lead active book-running managers for the IPO. The company is one of seven quantum computing firms and two quantum foundries in the US that received a share of $2 billion in federal incentives under the CHIPS and Science Act. This funding is aimed at advancing the development of quantum technologies. The company has signed a letter of intent for $100 million to fabricate low-loss integrated photonics and specialized optical components that are critical to trapped-ion technology. In addition, Quantinuum plans to collaborate with GlobalFoundries for essential semiconductor components and Monarch Quantum for integrated photonics. The quantum computing sector is gaining momentum, with a recent McKinsey report indicating that it could generate as much as $2.7 trillion in economic value by 2035. The report also noted that quantum companies are projected to generate over $1 billion in revenue by 2025, potentially increasing to $4.4 billion by 2028. In the broader context of the quantum computing industry, IBM announced a $10 billion investment in quantum technology over the next five years. Meanwhile, in Europe, French quantum start-up Quobly raised €115 million in Series A funding, and Finnish company IQM increased its private investment in public equity financing to over $146 million ahead of a planned SPAC merger and US stock market listing. These developments highlight the growing interest and investment in quantum technologies across the globe.
